Hello
I just want to know how to calculate the velocity from the given infomation: there is a dart shot from a dart gun and is flying towards an object.
For the dart to hit the object, it took 18 frames.
There is 240 frames in one second.
The distance is 45cm from where the dart was shot to the object.
How do you calculate the velocity in metres per second from the given infomation?
time=timeperframe*frames
=1/240*18=3/80 sec
velocity=distance/time=.45m/timeabove
To calculate the velocity in meters per second, we can use the formula:
Velocity = Distance / Time
First, we need to convert the distance from centimeters to meters. Since there are 100 centimeters in a meter, the distance in meters becomes:
45 cm = 45/100 = 0.45 meters
Next, we need to calculate the time it took for the dart to hit the object. Given that there are 240 frames in one second and the dart took 18 frames to hit the object, the time in seconds becomes:
Time = 18 frames / 240 frames/second = 0.075 seconds
Finally, we can use the formula to calculate the velocity:
Velocity = Distance / Time
Velocity = 0.45 meters / 0.075 seconds
Velocity = 6 meters/second
Therefore, the velocity of the dart is 6 meters/second.
To calculate the velocity in meters per second, we can use the formula:
Velocity = Distance / Time
Firstly, we need to convert the given distance from centimeters to meters. Since there are 100 centimeters in 1 meter, we can divide the given distance by 100:
Distance = 45 cm / 100 = 0.45 m
Now, we need to determine the time it took for the dart to hit the object. We are given that it took 18 frames for the dart to hit the object, and there are 240 frames in one second. So, we can calculate the time in seconds:
Time = 18 frames / 240 frames per second = 0.075 seconds
Finally, we can substitute the values for distance and time into the velocity formula:
Velocity = 0.45 m / 0.075 s = 6 m/s
Therefore, the velocity is 6 meters per second (m/s).
